Abstract: The present invention applies an electrochemical etching solution to a material layer, preferably a metal layer, disposed on a workpiece, in the presence of a current. This electrochemical etching solution supplies to the material on the substrate surface the species to form an intermediate compound on the surface that can be more easily mechanically removed as intermediate compound fragments than the material. By removing the intermediate compound fragments, the process allows more efficient use of the supplied current to form another layer of intermediate compound that can also be mechanically removed, rather than using the current to result in another compound on the surface of the material that eventually dissolves into the solution. In another aspect of the invention, such intermediate compound particulates are externally generated and used to mechanically remove the surface layer of the material. Such intermediate particulates do not contaminate, and thus allow for more efficient material removal, as well as plating to occur within the same chamber, if desired.

Abstract: A particular anode assembly can be used to supply a solution for any of a plating operation, a planarization operation, and a plating and planarization operation to be performed on a semiconductor wafer. The anode assembly includes a rotatable shaft disposed within a chamber in which the operation is performed, an anode housing connected to the shaft, and a porous pad support plate attached to the anode housing. The support plate has a top surface adapted to support a pad which is to face the wafer, and, together with the anode housing, defines an anode cavity. A consumable anode may be provided in the anode cavity to provide plating material to the solution. A solution delivery structure by which the solution can be delivered to said anode cavity is also provided. The solution delivery structure may be contained within the chamber in which the operation is performed. A shield can also be mounted between the shaft and an associated spindle to prevent leakage of the solution from the chamber.
